Like most.. i have the problem with the FOG after level 2. I downloaded a trainer for the game and played through the fog with god mode. the fog continued through level 3 and 4. after using the trainer to get through those 2 levels, it cleared up for level 5, and now i dont need the trainer! it is a pain because u cant really see, but by using the compass i was able to find my way. i have a radeon 9000 / 128 mg with newest drivers. hope this will help some of u to at least be able to play most of the game. after the fog, it seems like it will be worth the trouble, besides ... cant take it back since it has been opened, and local EB Games store stopped trading PC games. don't know how long the fog free levels will last. have only played a few more, but i have hope!
